JAMES C. PARKER, OF WOODSTON, KANSAS.

PRINTING ATTACHMENT FOR PAPER-ROLL HOLDERS.

To all whom it may concern Be it known that 1, JAMES C. PARKER, acitizen of the United States, residing at WVoodston, in the county ofRooks and State of Kansas, have invented a new and useful PrintingAttachment for Paper-Roll Holders, of which the following is aspecification.

The invention relates to a printing attachment for paper roll holders.

The object of the present invention is to improve the construction ofprinting attachments for paper roll holders, and to provide a simple,efficient, and comparatively inexpensive printing attachment, adapted tobe readily mounted in proper position on any ordinary paper roll holder,and capable of automatic operation by the same in removing the paperfrom the roll, and adapted to adjust itself automatically to the roll asthe latter decreases in diameter through the consumption of the paper.

Another object of the invention is to provide a printing attachment,adapted without the use of springs to cause the printing roll to exert arelatively heavy pressure on the paper roll, and at the same time toenable the inking roll to exert a relatively light pressure on theprinting roll.

The invention also has for its object to provide means for preventingthe inking roll from dropping into contact with any blank portions onthe printing roll, so that the entire surface of the printing roll oronly a portion thereof may be utilized for holding type.

\Vith these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in the claimshereto appended; it being understood that Various changes in the form,proportion, size and minor details of construction, within. the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the, drawings :Figure 1 is a front elevation of a paper roll holder,equipped with a printing attachment, constructed in accordance with thisinvention. Fig. 2 is a vertical sectional view on the line 22 ofFig.- 1. Fig. 3 is a front elevation of Specification of Letters Patent.

the attachment, the printing and inking rolls being held in an elevatedposition, so as to be out of contact with the roll of paper. Fig. 4 is atransverse sectional view. Fig. 5 is a detail sectional view of thelatch for locking the printing and inking rolls in an elevated position.Fig. (3 is a detail perspective view of one end of the latch and aportion of the main slides on which the same is mounted. Fig. 7 is adetail perspective view of the horizontal supporting frame or bracket.Fig. 8 is a detail perspective view of one of the main slides. Fig. 9 isa detail perspective view of one of the auxiliary slides.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

In the accompanying drawings in which is illustrated the preferredembodiment of the invention, the printing attachment is applied to thetop 1 of the main frame 2 of a paper roll holder by means of anapproximately Ushaped horizontal frame or bracket 3, composed of spacedsides 4 and a transverse connecting portion 5, and preferablyconstructed of flanged metal to secure the requisite strength andlightness, and at the same time to provide opposite flanges forsupporting spaced inclined guides (5. Instead, however, of supportingthe guides in an inclined position by the frame or bracket, whichoff-sets the said inclined guides from the top of the main frame, theguides may of course be mounted directly upon the main frame in avertical position at the upper portion thereof. The transverseconnecting portion 5 is provided with perforations 7 for the receptionof bolts 8 for securing the supporting frame or bracket to the top 1 ofthe main frame of the paper roll'holder, and the sides of the frame orbracket are provided with depending integral lugs 9, forming gage stopsand fitting against the rear edge of the top 1 of the main frame, inorder to position the attachment properly with relation to the paperroll 10 without having to measure the parts. The main frame 2 of thepaper roll holder is composed of spaced sides or standards, connected attheir upper ends by the top 1 and provided at the bottom with feet 12 toform an enlarged base, but any other desired construction of main framemay of course be employed. The roll 10 of paper is mounted on a woodencore or roll 13, which is journaled in suitable bearings 14 of the sidesor standards of the main frame. Also the paper roll holder may beequipped with suitable means for cutting or tearing the paper, but asthe specific construction of the paper roll holder does not constitute aportion of the present invention, and as the printing attachment isdesigned to be applied to various paper roll holders, furtherdescription and illus tration of the paper roll holder are deemedunnecessary.

The guides 6, which are inclined, are arranged radially with relation tothe axis of the paper roll, and they are constructed of suitable metal,being provided with parallel 'front and rear side flanges 15 and 16,form 1ng grooves and receiving main slides 17, which fit snugly betweenthe side flanges 15 and 16 which are movable upwardly and downwardlyalong the guides. The main slides 17 are oblong and are preferablyprovided in their outer faces with longitudinal channels 18 to reducethe frictional contact between the slides and the guides, and suitableanti-friction devices may be employed if desired. The guides, which arelocated above the plane of the bearings of the main frame, terminateshort of the roll of paper, as clearly illustrated in Fig. 2 of thedrawings, and they are secured at points intermediate of the ends byrivets 19, or other suitable fastening devices to the inner faces of theflanges of the spaced side port-ions of the U-shaped frame or bracket,which rigidly supports the inclined guides in their superimposedposition above the roll of paper. The guides are open at their upper andlower ends so that the slides may extend below the guides and alsotopermit the removal of the slides from the guides.

The main slides are provided at their lower portions with oppositetransversely alined bearing openings 20 for the reception of journals 21of a printing roller 22, and they are provided in their upper portionswith longitudinal grooves 23, extending downward from the upper ends ofthe main slides to points below the centers of the same, and forminglower shoulders or abutments 24, which are spaced from the bearingopenings 20. The grooves 23, which are ar ranged at the inner faces ofthe main slides, form guides for supplemental slides 25, which areprovided at their lower portions with transversely alined bearingopenings 26 for the reception of journals 27 of an inking roller 28,located above the printing roller and adapted to supply the same withink. The auxiliary slides 25 are oblong and are movable upwardly anddownwardly in the guide grooves 23, their downward movement beinglimited by adjustable screws 29,

mounted in threaded openings 30 in the lower ends of the auxiliaryslides, and projecting downwardly therefrom and arranged to rest uponthe shoulders or lower end walls 24 of the guide grooves 23. The screwslimit the downward movement of the auxiliary slides and are adapted tobe set to permit the inking roller to bear against the type 31 of theprinting roller with the desired pressure, and they prevent the inkingroller from dropping into contact with the body portion of the printingroller at any blank spaces between the type. By this construction, thereis no liability of applying ink to such blank portions of the printingmatter, and liability of smearing the paper with ink is eliminated. Thiswill enable the entire surface of the printing roller or only a portionthereof to be utilized for holding the type or equivalent means forprinting the advertising or other matter on the paper as it is unreeledfrom the device. The adjustable screws 29 also permit the use ofprinting rollers of various sizes, larger or smaller printing rollersbeing employed according to the quantity of matter desired to be printedon the wrapping paper. The adjusting screws 29 enable the auxiliaryslides, which carry the inking roller, to be raised or lowered toarrange the same at the proper elevation to cause the inking roller tooccupy the proper posit-ion with relation to 'the printing roller. Bymeans of the relative adjustment of the main and auxiliary slides, theymay be arranged so as to secure the proper contact between the inkingand printing rollers, when there is type in the printing roller and atthe same time prevent contact between the inking and printing rollerswhere there is no type in order to enable blank spaces to appear in theprinted matter without causing a smear. The inking roller, which may beof any de-' sired construction, is provided with a suitable absorbentpad 32, and the type or other printing means of the printing roll may beof any preferred construction and may be mounted on the printing roll inany desired manner. The main slides with which the printing roller isconnected are relatively heavy and cause the printing roller to bearagainstthe roll of paper wit-h considerable pressure, which isrelatively heavier than the pressure of the inking roller, as theauxiliary slides are light compared with the main slides. Also thepressure of the printing roller is the result of the combined weights ofthe printing and inking rollers with their respective slides, while thepres sure of the inking roller is produced only by the weightof suchroller and the auxiliary slides.

The nnreeling of the paper from the roll 10 rotates the latter, which,through frictional contact with the printing roller, 0p-

erates to rotate the latter, so that the type or other printing devicesthereof are brought into contact with the paper and caused to print onthe same. The inking roller is also rotated through frictional contactwith the printin roller, and the ink is thereby caused to be dlstributedto the type. The printing roller is provided at its ends, or otherconvenient points with flanges 22 of rubber or other suitable material,such as spring metal, arranged to contact frictionally with the roll ofpaper, whereby when the paper is unreeled from the paper roll, rotarymotion will be positively communicated to the printing roller andthrough the printing roller to the inking roller. The rings 22* cause asmooth uniform rotation of the printing roller and the type, which ispreferably constructed of rubber projects sufficiently beyond the planeof the peripheries of the rings 22 to secure a proper contact with thepaper. The paper roll engaging rings 22 also avoids any irregular motionof the printing roller at points or spaces Where there is no type, andprevent such portions of the printing roller from coming in contact withthe paper. WVhen it is not desired to use the printing attachment, thelatter is held in an elevated position, as illustrated in Fig. 3 of thedrawings, by means of a latch 33 consisting of a transverse rodconnected at its end portions with the main slides by plates 3% andprovided at an intermediate point, preferably adjacent to one end of themain slides with a projecting sleeve 35, forl'ning a handle and adaptedto enable the latch to be partially rotated to extend terminal arms 36into slots 37 of the front flanges 15 of the fixed inclined guides 6,and to withdraw the arms 36 from the said slots. The ends of the rodsare bent at right angles to form the terminal arms 36, and the mainslides are provided at their frontedges with recesses 38 in which theend portions of the latch are secured by the said plates 34. The plates34 are fastened in the recesses 38 by screws 39, or other suitablefastening devices, and they have angularly bent approxiniately L- shapedportions 40, fitted against the upper end walls of the recesses 38 andextending partially around the end portions of the latch. By thisconstruction, the latch is secured to the main slides and it serves as abrace or connecting means for the said slides. When the terminal arms 36are swung outward to their engaging position, as illustrated in Figs. 5and 6, they fit against the upper end walls of the recesses 38. Theupper end walls of the recesses form stops to limit the outward swing ofthe terminal arms of the latch, which is adapted to firmly support themain slides with the printing and inking rolls in an elevated position.

The auxiliary slides are connected by a handle 41, provided at thecentral port-ion with a U-shaped bend and having spaced terminalL-shaped portions 42, fitting in longitudinal grooves 43 in the upperportions of the auxiliary slides and engaging inclined openings 4% atthe lower ends of the grooves 43. The L-shaped portions 42 have inclinedterminal arms 45, extending upwardly and outwardly and passing throughthe inclined openings in the auxiliary slides and projecting beyond thesame, and extending into longitudinal slots 46 of the main slides. Theinclined terminal arms of the handle form hook-shaped portions, and theupper end walls 47 of the slots 46 of the main slides are inclined andextend upwardly and outwardly, whereby when the handle is grasped andlifted, the auxiliary slides will be moved upward until the projectingportions of the terminal arms engage with the inclined walls of theupper ends of the slots 4C6. The main slides will then rest upon theterminals of the handle and owing to the inclination of the parts theywill be held against the outward lateral movement. This will enable theslides and the inking and printing rollers to be removed from the fixedinclined guides without liability of the parts becoming disconnectedfrom the terminals of the transverse handle. The transverse handle alsooperates in the nature of a brace for spacing the top portion of theprinting attachment when the device is in use, but

the main slides are preferably connected by a transverse brace 1-8,consisting of a rod having its teri'ninals bent at right angles to formarms 49', which are secured in sockets 50 in the upper ends of the mainslides 17. The sockets are located at one side of the groove 23 in orderto arrange the brace be yond the plane of the auxiliary slides. Thisbrace 48 rigidly connects the upper end of the main slid es andcooperates with the handle T1, the latch 33 and the rollers in spacingthe slides and in maintaining the parts of the printing attachmentfirmly in proper position.
